first in my opinion ther is no mechanical problem with the tow handed froehand but ..... depending on a research on the most used stroke in tennis match .. they found that the forehand is the most stroke used in tennis match .. so how can you use take the very limited tow handed forehand as the most used stroke in that match

I cope quite well

Especially on returning I like getting the angles, and obviously my reach is limited but when I have to I use one hand. This way just feels more natural to me, yes i have to do a bit more running etc, but I think I can get enough speed on my forehand when I want to.

Just movement and stamina might be problems after a while. Using two hands does seem more reliable, but it could get tiresome after having to move that extra step because of the length of reach that two hands give you.
